Rental Secondary Suite in Sugarsnap, SE Calgary
A completed Grains Construction project in Sugarsnap, SE Calgary. Consultation, 2D structure design, permits, construction, inspections and handover, walked through room by room below.
Walkthrough
Inside this project
From the street, nothing changed
This is the home the work went into. Almost every square foot we added here already existed, sitting unused below the main floor. No excavation, no extension, no change to the roofline or the footprint. From the curb the house looks exactly as it did before, which is precisely the point.
The exterior tells you what makes lower level work so efficient. The foundation, the walls and the roof are already built and already paid for. Everything that follows happens inside that shell, which is why this kind of project avoids the cost and the disruption of building outward.
A separate entrance, built properly
This is the detail that turns a finished basement into an independent dwelling. The entrance gives the unit its own address in practice: occupants come and go without ever passing through the main home, which is both a code requirement and the thing tenants care about most.
A self contained unit needs its own entrance, and it has to be built rather than improvised. That means a compliant stairwell, proper drainage at the base, a landing, handrails and an exterior door detailed to keep weather out. This entrance was framed, waterproofed and finished as part of the permitted scope.
The main living area
This is the room the whole layout is built around. Ceiling height, beam positions and duct runs were measured before framing so the main living area got the clear, uninterrupted span, and the bulkheads and service clearances were pushed into circulation and storage space where they are not noticed.
Recessed lighting is laid out on a grid rather than dropped in wherever joists allowed, and the flooring runs continuously through the space to make it read larger. Details like that are decided at drawing stage, which is why the finished room feels planned instead of assembled.
A full kitchen, not a kitchenette
The layout keeps the working triangle tight so the space functions properly rather than just looking complete in a photograph. Backsplash, counter and cabinet hardware were specified together, and the appliance package was planned into the elevation from the start rather than squeezed in at the end.
A full kitchen with cabinetry, counters, sink and appliance connections on their own dedicated circuits. Plumbing was brought in and tied to the existing stack, and the range and dishwasher were wired by licensed trades and inspected before the cabinets went in.
The bathroom
The bathroom is where shortcuts show up first, usually two winters later. Behind the tile there is a proper waterproofing system on the wet walls, the correct substrate and a floor built to fall to the drain. Mechanical extraction is ducted to the outside rather than into the joist space.
Plumbing rough in was inspected before anything was closed up, and the finishes went on afterwards: tiled shower, glass enclosure, vanity, mirror and fixtures. Getting the sequence right is what keeps a basement bathroom dry for its whole life.
Every bedroom, every EGRESS WINDOW
This is the single most common reason an existing basement fails to legalise. Rooms get called bedrooms without a compliant opening, and the fix means saw cutting the foundation. Building the opening correctly the first time is far cheaper than correcting it afterwards.
Every bedroom below grade needs a compliant EGRESS WINDOW, sized so an adult can get out and a firefighter can get in, with the window well dimensioned to match. It is not optional and it is not a detail you can add later without cutting concrete, so it is designed in from the first drawing.
Laundry, planned in
Laundry was designed into the layout rather than left to wherever there happened to be room. The unit gets its own washer and dryer, with the water supply, drain and dedicated circuit run during rough in and the dryer vented properly to the exterior.
For a self contained unit this matters more than it looks. Shared laundry means shared access through the main home, which undermines the independence the whole build is meant to create.
Access, done to code
Finishing the stairs properly also does a lot of quiet work on how the whole level feels. It reads as part of the home rather than the way down to a basement.
Stair geometry is governed by code: consistent rise and run, minimum headroom, and a handrail at the required height. Existing basement stairs frequently fail one of those, and correcting them is part of bringing the level up to standard.

Scope Of Work
What this build involved
Independent Entrance
A separate, code compliant entrance so the unit operates without any access through the main dwelling.
Full Kitchen
Complete kitchen with cabinetry, counters, sink and appliance connections on dedicated circuits.
Bathroom & Laundry
Full bathroom for the suite, with laundry provision planned into the layout rather than added later.
Egress & Fire Safety
Egress window to code in every bedroom, rated fire separation, and interconnected smoke and carbon monoxide alarms.
Durable Finishes
Flooring, paint and fixtures specified for rental wear and straightforward turnover between tenants.
Permits & Inspections
Full permit package and every required City inspection, so the suite is legal on paper as well as in practice.
What can a legal basement suite rent for in Calgary?
Legal basement suites in Calgary have commonly rented in the region of $1,500 to $1,750 per month, moving with size, finish, parking and location. Rental markets shift, so run your own numbers on current listings before committing.
Can I rent out a basement suite that was never permitted?
You are taking real risk if you do. Unpermitted suites can be ordered closed, can void or complicate insurance claims, and routinely cause problems at resale. Legalising an existing space is often possible, and we can tell you what it would take after looking at it.
Does building a legal suite change my property taxes or insurance?
Insurance should be updated to reflect that the home contains a suite, and you should tell your insurer. Speak to your provider and to the City about your specific situation, since it depends on the property.
Who handles the permits and inspections?
We do. Development and building permits, the drawing package, and every required inspection through to final approval are part of the job rather than something handed back to you.
Is there funding available for a rental suite?
The City of Calgary Secondary Suite Incentive Program has reimbursed eligible owners up to $10,000 toward a legal, registered suite. Programs and their rules change, so we check what is current with you at the free consultation.
